A nurse is preparing to administer carbamazepine suspension 150 mg via NG tube every 6 hr. The amount available is 100 mg/5 mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

Placing the client's arms raised above her head with her legs elevated on pillows (choice A) is not the correct position for a lumbar puncture. This position does not facilitate proper alignment of the spine and may hinder the procedure.

Choice B rationale:

The Trendelenburg position with the body in Sims' position (choice B) is not the correct position for a lumbar puncture. This position is not commonly used for lumbar punctures and may not provide the necessary anatomical alignment for a successful procedure.

Choice C rationale:

Placing the client prone with her arms at her side and her legs extended (choice C) is not the appropriate position for a lumbar puncture. This position does not allow for proper access to the lumbar region and may impede the procedure.

Choice D rationale:

The correct position for a lumbar puncture is to have the client flex their head to the chest and pull their knees up to the abdomen (choice D) This position maximizes the space between the lumbar vertebrae, making it easier for the provider to access the subarachnoid space for cerebrospinal fluid collection.

The correct answer is Choice B.

Choice A rationale: This client has a new diagnosis and requires initial teaching about meal planning, which is typically a responsibility of a registered nurse (RN) due to the need for specialized knowledge and teaching skills.

Choice B rationale: This client has a low urinary output, which needs to be monitored, but the care required is within the scope of practice of a licensed practical nurse (LPN). They can manage and report findings to the RN.

Choice C rationale: This client has a low respiratory rate postoperatively, which could indicate respiratory depression. This requires immediate assessment and intervention from an RN, who can make complex clinical judgments and initiate appropriate care.

Choice D rationale: This client needs an admission assessment, which includes comprehensive initial evaluation. An RN is required for this as it involves detailed assessment, care planning, and initiation of care.
